3. Stripped of rank by usurper after refusing to participate in bloody purge, quests for mythic Death Ray of Redemption believed incorporated into statuary in Underworld chaos temple
4. Court-martialed for treason after sparing the life of defeated cephalopod wizard, death sentence commuted following pledge to throw away life battling Underworld horrors

6. Brain damaged in heroic melee with hostile colossus totally out of her league, decision-making now highly erratic, pursues the fungus-wizard famous for regeneration magic
7. Adventuring companions grew weary of sanctimony: beaten, poisoned, back-stabbed, stripped of goods, thought dead, deposited in remote Underworld zone, sworn to find/punish turncoats believed on extended treasure-hunt
8. Lost mind after messing around with alien intelligence enhancing device, occasionally brilliant from out of nowhere, mostly incoherent, holy mission/delusional compulsion to locate, destroy as-yet unknown relic of evil, will attempt to eliminate any magic item found to be on the safe side
9. Betrayed by secretly evil wizard, teleported to center of earth, slowly making way back to surface while gathering strength, dubious allies, for eventual assault on wizard's HQ
10. Face burned off by dragon, now masked hero of the Underworld, known to rescue youths of evil but draws line at grown ups
11. Disgraced after drunken, murderous spree at Imperial casino, can never show face in the big city again, seeks atonement via evil-bashing
12. Hung around with crew of murderhobos too long, it rubbed off resulting in unforgivable acts, deity furious, knight sent below to atone with non-stop violence against cults of evil
